Sulphur deactivates the various catalyst surfaces found in 3-way catalytic converters on petrol engines and diesel oxidation catalysts on diesel engines. This decreases catalyst efficiency and causes harmful exhaust gas compounds to enter the atmosphere.
The role of sulphur in the formation of acid rain and the resultant harmful impact on the environment is well known, the reduction of sulphur levels has helped to minimise this negative impact.
Thanks to our synthetic fuel production process, Sasol Turbofuels from our Secunda production facility are inherently sulphur-free and are the only fuels in South Africa that consistently meet the most stringent international sulphur content specifications (10ppm).
